Stellar Index v0.44.1

[v0.44.1] — 2026-08-25

Tested against Stellar protocol 22.

Added

• Live account-movements feed: the /accounts/{id} movements view now
  auto-follows the ledger tip — an SSE-nudged refetch (~4s coalesced,
  shared tab-wide) gated to the first page so a keyset walk into history
  is never yanked back, with a 20s fallback poll if the stream drops.
  Classic-asset movement lag is cut from ~5min to ~30s by tightening the
  incremental cap67 derive timer (the derive runs in ~0s per fire; true
  up-to-the-second via a continuous follow-worker is a follow-on). (#172)

Fixed

• cap67 account-movements derive could permanently lose movements
  under lake pressure. The LiveSink drops whole ledgers under buffer
  pressure, leaving holes near the tip, but the derive resolved its upper
  bound with raw MaxLedger and advanced its watermark past any hole
  with no trailing re-derive — so a dropped ledger's classic/native
  account movements were never revisited (the raw lake self-heals via
  ch-live-catchup; this derive did not → a permanent gap in account
  history). Now clamped to ContiguousWatermark (mirroring the real-time
  projector), so the derive stalls at a hole until catch-up heals it —
  delayed, never lost. Found by an adversarial audit of the
  real-time-movements plan. (#174)
• /v1/divergence (the per-reference divergence board) returned 500 on
  every request — ListDivergenceLatest wrote its trailing-window
  filter as now() - ($1 || ' days')::interval, which makes Postgres
  infer $1 as text, but the handler passes sinceDays as an int.
  pgx v5 has no int→text encode plan, so the query failed before
  executing (unable to encode 7 into text format for text (OID 25)).
  The window is now make_interval(days => $1), which types $1 as an
  integer. Adds a regression test that forbids the text-concat form. (#176)
• The volume_character rollup worker refreshed the all-asset 14-day
  account-structure roll every 15 minutes; each pass is a multi-minute
  full scan of the trades hypertable (72M rows/7d), so it ran
  effectively continuously and starved the customer API (the p99 2259ms
  regression introduced in v0.44.0). The cadence is now 6h and the roll
  caps its own max_parallel_workers_per_gather + statement_timeout so
  a single refresh can't monopolize the primary. (#175)
• Explorer pill contrast: category / venue / type chips now route through
  the adaptive design tokens instead of hard-coded colors, fixing
  low-contrast pills in the dark theme. (#173)
